Roof Replacement in Denver, CO — Denver Roofing Team

Trust, transparency, and craftsmanship define every roof replacement we do at Denver Roofing Team. We treat your home like our own, starting with a thorough inspection and ending with a system built to handle Denver's intense sun and sudden hailstorms. You get a straight answer on what your roof needs and a crew that shows up on time.

What Roof Replacement Involves

A full residential roof replacement is a complete system overhaul, not just slapping on new shingles. We start by tearing off every layer down to the decking — no shortcuts, no second layers buried underneath. Once the deck is exposed, we inspect every sheet of plywood for rot, delamination, or hail damage, replacing any compromised sections with new CDX plywood. Next comes the underlayment: we use a synthetic underlayment like GAF Deck-Armor or Owens Corning ProArmor, which outperforms traditional felt in tear resistance and UV protection. At every valley, eave, and penetration, we install ice-and-water shield — a self-sealing membrane that prevents leaks from ice dams and wind-driven rain common in Denver's freeze-thaw cycles. For the shingles themselves, we install Owens Corning Duration architectural shingles (with SureNail strip for enhanced wind resistance) or CertainTeed Landmark Pro for a premium laminated look. In high-hail areas like Capitol Hill or Cherry Creek, we recommend Class 4 impact-resistant shingles such as Malarkey Vista, which resist hail impact cracking and granule loss. Ridge vents at the peak, paired with soffit intake vents, create a balanced airflow system that exhausts attic heat and prevents moisture buildup. The final step is manufacturer warranty registration — we handle the paperwork so you get the full 25- to 50-year coverage.

Signs You Need Roof Replacement

Your roof gives clear signals when it's time for replacement. Missing or loose shingles after a windstorm expose the deck to moisture and accelerate decay. Granules in your gutters — those black sand-like particles — mean the shingle's protective coating is eroding from UV degradation at Denver's 5,280-foot altitude. Dark patches or algae streaks on the south-facing slopes indicate moisture retention and granule loss, not just cosmetic staining. Ceiling stains or drips inside your attic are a red flag for ice dam back-up or failed underlayment. Curling or cupping shingle edges suggest thermal cycling — the constant expansion and contraction from 90-degree days to below-freezing nights — has fatigued the asphalt. Finally, if you see daylight through the roof deck from inside the attic, the wood has rotted or warped, and replacement is overdue.

Our Roof Replacement Process

Step 1 — Free Inspection and Damage Report: We climb onto your roof and document every issue with photos — curled shingles, granule loss, hail impact marks, decking soft spots. You get a written report with repair recommendations prioritized by severity.

Step 2 — Material Selection and Permitting: We walk you through shingle options — Owens Corning Duration, CertainTeed Landmark Pro, or Malarkey Vista for impact resistance. We pull the required reroof permit from Denver County (required if more than 50% of the roof is replaced) and handle any structural-change drawings if you're adding dormers or skylights.

Step 3 — Tear-Off and Decking Repair: Our crew strips the old shingles and underlayment, then inspects every square foot of decking. We replace rotted or hail-damaged plywood with new CDX, and install ice-and-water shield at eaves, valleys, and all penetrations.

Step 4 — New System Installation: We install synthetic underlayment across the entire deck, then lay the architectural shingles with proper offset and fastening per IRC R905.2. Ridge vents are installed at the peak with a continuous vent strip, and soffit vents are checked for adequate intake airflow.

Step 5 — Cleanup and Final Inspection: We magnetically sweep the yard and gutters for nails and debris, haul away all waste, and walk the roof with you to confirm satisfaction. We then register your manufacturer warranty — 25 years for Owens Corning Duration, 50 years for CertainTeed Landmark Pro.

Cost Considerations in Denver

Roof replacement costs in Denver typically range from $450 to $750 per square (100 square feet) for architectural shingles, depending on roof complexity, pitch, and number of penetrations. A standard 30-square home (about 3,000 square feet) runs between $13,500 and $22,500. Class 4 impact-resistant shingles like Malarkey Vista add $100 to $200 per square but pay off quickly in Denver's hail-prone climate — the 2017 hailstorm alone caused over $2 billion in damage. Decking replacement adds $100 to $150 per sheet, and structural changes require stamped engineer drawings at $500 to $1,500. We provide a transparent, itemized quote with no hidden fees.

Warranty & Insurance

Every roof replacement includes a manufacturer warranty — 25-year non-prorated coverage on Owens Corning Duration shingles, and a 50-year limited warranty on CertainTeed Landmark Pro. We also offer a 10-year workmanship warranty covering installation defects like nail pops or flashing failures. If you're filing an insurance claim after a hailstorm, we help document the damage with detailed photos and provide a scope of work that meets carrier requirements. We work directly with your adjuster to ensure you get the coverage you deserve.

Why Choose Denver Roofing Team for Roof Replacement in Denver?

Denver sits at 5,280 feet above sea level, which means UV radiation is 30% more intense than at sea level — shingles age faster here. Our crews are trained to select materials rated for this environment, like Owens Corning Duration with SureNail for wind resistance and Malarkey Vista for hail impact. We know Denver's building codes — IRC R905.2 mandates underlayment per slope and deck type, and structural changes need stamped engineer drawings. We serve neighborhoods from Capitol Hill to Five Points, Cherry Creek to Washington Park, Highland to Baker, and understand the unique challenges of mid-century brick ranches, Victorian bungalows, and post-war suburban split-levels. Hail season runs May through September, and we stock impact-resistant materials year-round. When you hire us, you get a local crew that shows up, does the job right, and stands behind the work.

Signs You Need Roof Replacement

Missing or Loose Shingles

Windstorms common in Denver can rip shingles off, leaving the deck exposed to moisture. This accelerates rot and leads to interior leaks within weeks.

Granules in Gutters

Black sand-like granules in your downspouts mean the shingle's protective coating is eroding from UV radiation at 5,280 feet. Once the granules are gone, the asphalt breaks down quickly.

Dark Patches or Algae Streaks

South-facing slopes show dark streaks from moisture retention and granule loss. This isn't just cosmetic — it signals the shingle is losing its ability to shed water.

Ceiling Stains or Drips

Water stains on your ceiling or attic rafters indicate ice dam back-up or failed underlayment. Denver's freeze-thaw cycles make this a seasonal risk from November through March.

Curling or Cupping Shingles

Thermal cycling — 90-degree days followed by below-freezing nights — causes shingle edges to curl or cup. This exposes the nail heads and underlayment to moisture and wind.

Daylight Through the Deck

If you see daylight from the attic through the roof deck, the plywood has rotted or warped from long-term moisture exposure. This requires immediate decking replacement.
